Overview
SIST-TP CEN ISO/TR 6026:2023 provides a comprehensive pre-study on the use of vehicle licence plate information and automatic number plate recognition (ANPR) technologies in electronic fee collection (EFC). The standard analyzes the legal, technical, and functional contexts of using licence plate numbers (LPN) in EFC schemes. It offers an in-depth gap analysis of current EFC standards and outlines a roadmap for standardizing the application of ANPR in fee collection systems, with a special focus on the European electronic toll service (EETS) model.
This document is aimed at facilitating common understanding and interoperability among traffic authorities, toll service providers, and technology vendors, enhancing the efficiency and reliability of electronic tolling based on vehicle identification.
Key Topics
- Legal Context: The study examines how licence plate characteristics, jurisdictional requirements, and relevant regulations underpin the use of LPNs in electronic tolling. It details how legal mandates define the design, placement, and visibility of plates, affecting ANPR system design and operation.
- Technical and Functional Analysis:
- Architectural aspects of ANPR-based EFC, including information exchanges between stakeholders such as toll service providers, registration authorities, and users.
- Overview of ANPR system components: roadside equipment, image acquisition, optical character recognition (OCR), and back-office processing.
- Challenges such as plate readability, environmental factors affecting recognition, and plate tampering or aging.
- Use Cases and Business Scenarios: The standard identifies practical use cases, from LPN-based user recognition and toll enforcement to handling exceptions and ensuring payment compliance.
- Gap Analysis: The document reviews existing EFC standards, pinpoints gaps in technical interfaces, performance metrics, data exchange, and security, and recommends areas for improvement to support robust ANPR-based schemes.
- Standardization Roadmap: Provides actionable recommendations for closing identified gaps and outlines steps toward harmonized implementation of LPN and ANPR technologies within EFC.
Applications
Electronic fee collection using ANPR technologies delivers several practical benefits in the road transport sector:
- Automated Tolling: Enables contactless toll collection without the need for onboard units, supporting open road tolling where stopping is not required.
- Traffic Management: Integrates with intelligent transport systems (ITS) for congestion zone charging, commercial vehicle monitoring, and enforcement of restricted zones.
- Interoperability: Enhances cross-border movement by complying with EETS models, ensuring vehicles from different jurisdictions can be reliably identified and charged.
- Law Enforcement: Supports ancillary applications such as security monitoring and detection of illegal license plates or stolen vehicles.
- Operational Efficiency: Reduces administrative costs and increases throughput at toll stations by minimizing manual checks.
